Okay, let’s tackle this. So Young Koh has 11 years of experience in leadership roles, which is a significant amount of time. He has skills like project management, marketing strategy, and negotiation, which are in demand. Location is Buena Park, California, which is a hub for various industries. Considering his experience and skills, I would estimate his hourly rate to be around $125. This is lower than what someone with similar experience in a corporate setting might charge, but it's still a competitive rate for a executive with his background in operations management and team leadership. Some executives with similar experience might charge $150-$200 per hour, but Koh's experience in event management and hospitality might bring his rate down slightly.
